You can power any of them.
The best one only needs 1 amp at 12 volts.
Specifications: 80x80x38mm, -->80.16<-- CFM @ 5700 RPM,
52.5 dBA, 10.80w .90 Amp, 12v DC, 4-pin Molex connector.
Unless you have a large number of drives, HDs/ CDROMs etc,
I don't think you have a problem.
If you get the BIG ONE let me know how loud it is.
I have a Swiftec too.
